A delicious lentil salad with halloumi, beetroot, and a red onion dressing is a fantastic lunch salad. A sharp and flavorful dressing that perfectly matches grilled halloumi.
A lentil salad with grilled halloumi is extra tasty with a homemade red onion dressing, but you can also use a different and quicker dressing. The sharp taste of red onion gives this salad a full flavor that is different from what you are used to.
You can also use other types of lentils, or use dried lentils and cook them yourself until they are soft. The exact cooking time of lentils varies by type and also depends on the age of the lentils. Older dried lentils take longer to cook.

First, cut out the segments from the grapefruit so you can use the juice for the dressing. The easiest way to do this is by cutting off the top and bottom of the grapefruit first. Then cut the peel and white part around it. Now cut out the segments between the membranes and squeeze the juice out of the remaining membranes.
Start making the dressing by blending a small half red onion with 1 teaspoon of mustard and about 3 tablespoons of grapefruit juice.
Add 5 tablespoons of good olive oil and season with black pepper and salt.
If needed, wash the arugula and remove excess water with a salad spinner.
Wash the cherry tomatoes and cut them in half. Cut the cooked beetroot into cubes.
Place a handful of arugula on each plate and distribute the beetroot, grapefruit segments, cherry tomatoes, and beluga lentils over it.
Heat a grill pan over high heat and meanwhile slice the halloumi. Drizzle the halloumi with olive oil and grill it on both sides until grill marks are visible.
Finish the salad with the red onion dressing and grilled halloumi, enjoy!
What are beluga lentils and can I replace them?
Beluga lentils are small black lentils. Because they are so small, they take less time to cook than most other types of lentils.
Beluga lentils are rich in protein and are sometimes compared to caviar because of their color.
What else is red onion dressing good with?
If you have some leftover red onion dressing, it is also delicious with a salad with quail eggs.
